BEAM-SCALE.

SPECIFICATION forming part of Letters Patent No. 525,517, datedSeptember 4, 1894.

Application tiled April 4, 1894. Serial No. 506.328. (No model.)

To all whom it may concern:

Be it known that I, FRANK M. SMILEY, a citizen of the United States,residing at Goshen, in the county of Elkhart and State of Indiana, haveinvented certain new and useful Improvements in Beam-Scales; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in beam scales or attachmentstherefor; and it has for its general object to provide a beam pea orpoise adapted when it is adjusted on the beam to balance a weight, toindicate to a person knowing the price per pound of such weight, theexact price or value thereof.

Other objects and advantages will be fully understood from thefollowing` description and claims when taken in connection with theannexed drawings, in which- Figure 1, is a front elevation of myimproved pea or poise in position upon a scale beam. Fig. 2, is adiametrical section of the same taken in the plane indicated by the lineoc, 0c, of Fig. 1. Fig. 3, is a front elevation of the device with therotary indicator or index removed and the sections of the dials spreadapart, and Fig. 4, is an elevation of the reverse side of the outerdial.

Referring by letter to said drawings:-A, indicates an ordinary scalebeam having rack teeth as a, upon its upper edge and B, indicatesmy'improved pea or poise which is designed to be adjusted upon the beamA, in the usual manner. This pea or poise B, comprises a body C, and thesaid body which rests at one side of the beam and is preferably of acircular form as shown, affords a bearing for the central lateral shaftD, and is provided with lateral studs or bolts E, E', which arepreferably headed as illustrated and are designed to support the dialsF, F, in the manner shown. The said dials F,F, are similar inconstruction and they respectively comprise two semicircular sections b,which have their contiguous edges notched as indicated at d, and e, toform elongated openings for the passage of the shaft D, and the stud orbolt E, and also have their peripheral edges notched adjacent to theirlower ends as shown at f, to receive the studs or boltsE, and a link c,to which the upper ends of the sections b, are pivotally connected asshown. By having the dials of the peculiar construction just described,the outer dial may be conveniently removed to expose the inner one andboth dials may be reversed upon the studs when they are provided withfigures upon both sides as will be presently described. I would have itunderstood however that when but one dial is employed and figures areprovided on but one side thereof such dial might be of any suitableconstruction and might be connected to the body C, in any approvedmanner.

To remove the dials F, F', for the purposes above stated, it is simplynecessary to first raise them so as to disengage their notchesf, f, fromthe studs or bolts E', and then spread them apart as illustrated in Fig.3, to disengage them from the shaft D, and the stud or bolt E. Theelongated notches d, and c, permit of the dials being moved verticallyand it will therefore be obvious that said dials may be readily raisedand disengaged from the bolts E', as above described. Y

G, indicates a gear wheel which is iixedly mounted on the shaft D, andengages the teeth a, of the beam in order that when the pea is moved onthe beam, the shaft will be rotated, and H, indicates the rotaryindicator 0r index which is fxedly mounted on the outer end of the saidshaft. This indicator H, as better shown in Fig. 1,preferably comprisesthe arms I, I I2, I3, which are by preference tangentially disposed tothe shaft D, although they might be radially disposed if desired, theparallel circular wires o', which are connected to the arms I, I, andI2, the parallel circular branches, which extend from the arm I2, andmay if desired be terminations of the wires i', and the parallelcircular branches lo, which extend from the arm I3, as shown. Thesebranches j, 7o, of the arms I2, I3, are provided with graduations andhave such graduations numbered from one to five to represent cents, andthe arms I2, I3, are provided at points opposite the branches j, 7c,with iigures representing the price per pound of the several substanceswhich the scale is designed to weigh. l The arm I2, is provided with theprice ligures 4%, Al, 4, 3%, and 3, and is designed to be employed inconjunction with the figures on the obverse sides of the two ICO dialsF, F', while the arin I3, is provided with the price figures 5;'1, 55A,521,-, 5, and di, and is designed to be employed in conj unction withthe figures on the reverse sides of the dials. The dial F, is providedupon its obverse and reverse sides with the circular scales m, which aredivided into eight divisions representing` pounds and have suchdivisions numbered from one to eight as shown in Figs. l, and il, andthe dial F', is provided upon its obverse and reverse sides with similarcircular scales fn, the eight divisions of which however are numberedfrom eight to sixteen. The said dial F, having the circular' scale m,divided into eight divisions is designed for use when the substance tobe weighed does not exceed eight pounds, and when it is not necessary tohang a weight on the beam, while the dial F', having the circular scalefn, is designed for use when the substance to be weighed ex ceeds eightpounds and when it is necessary to hang an eight pound weight on thebeam.

Both dials are provided upon their obverse and reverse sides within thescales m, n, with the groups of figures representing various amounts.The obverse side of the dial F, for instance is provided with the groupsof figures 5, lO, l5, 20, 25, 30, and 85, arranged in lthe manner orsubstantially the manner shown, while the reverse side of said dial isprovided with the groups of figures 5, l0, l5, 20, 25, 30, 35, 40, ande5, arranged in substantially the manner shown. The dial F', which asbefore stated, is designed for use when substances exceeding eightpounds in weight are to be weighed is provided upon its obverse facewith the groups of figures 30, 35, 40, 4:5, 50, 55, 60, 65, and 70, andupon its reverse face with the groups of figures 40, 45, 50, 55, GO, 65,70, 75, 80, 85, and 90.

In the practical embodiment of my invention the rack upon the beam A,should be of such a length and the gear wheel G, of such a size that theindicatororindex H, will make but one complete revolution when the peaor poise is moved the full length of the rack. Care must also be takento have the dials F, F",properly adj usted, that is to sayif the priceper pound of the substance to be weighed is found on the arm I2, of theindicator, the obverse side of the dial F, or the dial F', according tothe approximate weight of the substance should be arranged next te theindicator, while if the price per pound of the substance is found on thearm I3, of the indicator, the reverse side of the dial F, or the dialF', according to the approximate weight of the substance should bearranged next to the indicator. I would also have it understood that thecircular scales m, upon the obverse sides of the dials F, F', are soarranged with rcn spect to the arm I2, the beam D, and the gear wheel G,as to enable the said arm l2, to indicate the weight as well as thetotal cost of the substance, being weighed, when the obverse side ofeither dial is employed, while the circular scales n, upon the reversesides of the dials F, F', are so arranged with re spect to the indicatorarm 1"", the beam D, and the gear wheel G, as to enable the said arm lg,to indicate the weight as well as the total cost of the substance beingweighed when the obverse side ot either dial is employed. I wouldfurthermore have it understood that while the dials F, F', are adaptedto be removed and reversed in position, yet their portions which areuppermost in one position, are uppermost in the other position; andsince both dials are in position upon the poise when the same is in use,the adjustment of the dials will not affect the weight of the poise.

With this understanding of the device, the operation will be fullyunderstood from the following description: "When a substance, weighingfor instance five pounds, and worth four and one-half cents per pound isplaced upon the platform of the scale, the obverse side of the dial F,should be presented tothe indicator after which the pea is moved uponthe beam until it balances the weight, when the arm i2, of the-indicatorpointing to the figure 5, of the scale on, of the dial F, will indicatethe weight of the substance. Now if the weigher knows the price perpound oi the substance he may readilyascertain the price of the whole byreferring to the figures on the dial nearest the right hand edge of thearm l2. The price being 'four and one halt' cents per pound, theoperator will Find a figure 2O below the branch j opposite the tiguressi, which figure 20, will rest at a point midway the two and three centmarks of said branch indicating that five pounds of the substance atfour and one half cents per pound is worth twenty two and one haltcents. If the substance be worth for instance four and one quarter centsper pound, the operator will nd a figure 20, below the branchj, oppositethe figures 411;, which figure ZO, will rest at a point between the l,and 2 cent marks of said branch and adjacent to the l ct. mark so astoindicate that the price of the substance is twenty one and a quartercents. wWhen the price per pound of the substance to be weighed is foundon the arm I3, instead of the arm I2, the dial F, should be reversed soas to present its side shown in Fig. 1t, to view, and when this is donethe arm I3, will not only indicate the total price of the substanceweighed but will in conjunction with the scale u, indicate the number ofpounds. Vhen the weight of the substance exceeds eight pounds and it isnecessary to hang an eight pound weight on the beam, the dial F, isremoved so as to present the dial F', to view. This dial F', is used inthe saine manner as the dial F, that is to say that if the price perpound of the substance is found upon the arm I2, such arm will be usedin conjunction with the obverse face of the dial to indicate the numberof pounds and the price of the whole, while if the price per pound is onthe arm I3, such arm will be used in conjunction with the reverse faceof the dial.

The arms I, I', of the indicator II, perform no function when but twodials are employed. Said arms I, I', are however designed for use whenthe poise is provided with four dials, in which case said arms would beprovided with scales of prices different from those of the arms 12, I3,and the wires 1l, intermediate of the arms would be provided withnumbered notches, while the two additional dials would b e provided upontheir obverse and reverse sides with groups of gures representingamounts and would also be provided with circulai` scales the same as thedials F, F.

It will be seen from the foregoing that my improved device while verysimple enables a weigher to readily ascertain the price of the substanceweighed without taking up the l time necessary to figuring. It Will alsobe noticed that the device is very simple and easily adjusted and thatit embodies no coniplicated parts likely to get out of order which is adesideratum.

When my improved device is to be employed for weighing certainsubstances, the prices of which might be placed upon a single arm, oneindicator arm might be employed in conjunction with a single dial whichmight be connected to the body C,in any approved manner. I therefore donot desire to be understood as confining myself to the specificconstruction of dials herein set forth, nor do I desire to -be confinedto the specic construction and relative arrangement of the other partsas such changes or modifications may be made in practice as fairly fallwithin the scope of my invention.

Having described my invention, what I claim is l. The computing poise orpea, comprising abody or frame, two removable and reversible dialsrespectively formed 0f two sections connected together and supported onthe body or frame, arms having lateral branches i, at intervals in theirlength, a wheeladapted to engage a scale beam, and mechanismintermediate of said Wheel and the indicator arms, all substantially asand for the purpose set forth.

2. A computing device comprisingl a body or frame, arotary shaftjournaled in the body or frame and carrying an indicator and a removabledial formed of two sections connected together and adapted to straddlethe rotary shaft and also adapted to engage projectioiis on the body orframe, substantially as and for the purpose set forth.

3. A computing device comprising a body or frame having lateral studs asE, E', a dial formed of two sections loosely connected together andadapted to engage the studs E, E', and a rotary indicator, substantiallyas and for the purpose set forth.

4. A computing device comprising a body or frame having lateral studs asE, E', two dials respectively formed of two sections loosely connectedtogether and adapted to engage the studs E, E', and an indicator mountedon the shaft journaled in the body or frame and consisting of two armshaving lateral, circular branches, substantially as and for the purposeset forth.

5. The combination with a scale beam, of-a computing poise or peaadapted to slide on the beam and comprising a body or frame havinglateral studs as E, E', two dials respectively formed of two sectionsloosely connected together and adapted to engage the studs E, E', ashaft journaled in the body or frame and extending between the dialsections, an indicator mounted on said shaft and consisting of two armshaving lateral, circular`branches, and a wheel also mounted on saidshaft and engaging the beam, substantially as and for the purpose setforth.

In testimony whereof I affix my sigiiaturein presence of two witnesses.
